Patent CA-2038592-A1 (CA)
Inventor: HYODO RYUJI
IPC: H04L12/70
Filed: 1991-03-19
Abstract: A synchronization circuit for asynchronous transfer mode (ATM) cells transferred in an ATM communication system, wherein the synchronization circuit receives and holds in a bit serial manner the input bit trains constituting the received ATM cells by a shift register unit, performs a cyclic redundancy check (CRC) operation in a bit serial manner on the held input bit trains by a continuous CRC arithmetic unit in accordance with a simplified CRC operation process different from the usual CRC operation process, and performs the necessary synchronization control upon receiving the CRC arithmetic operation result at a synchronization control unit, thereby enabling CRC arithmetic operations to be performed continuously and by simple hardware on the headers in the ATM cells.
Patent CA-2039364-A1 (CA)
Inventor: HARTUNG JOSEPH C
IPC: G06F12/00
Filed: 1991-03-28
Abstract: A method for selecting data storage media for demount in an automated storage library,  and an automated storage library  and  program  product  therefor  are  disclosed. Preemptive demount of storage media is permitted when all peripheral storage devices in the library are occupied and one or more of such devices remains inactive for a predetermined time.   Storage media may be demounted to service existing mount requests, provided the peripheral storage  devices  in  which  the  media  are  mounted  are inactive.  There is also a need, however, to ensure the availability of an empty device to service future mount requests, particularly in libraries having only a single gripper mechanism. Thus, even when no mount requests are pending, the status of the peripheral storage devices is continually monitored.  If the peripheral storage devices are all occupied, and one or more of such devices remains inactive for the predetermined time, the least recently used storage medium is demounted and transferred to a storage cell in the library.

Title: Reduced gas holdup in catalytic reactor
Inventor: BUTTKE ROBERT D
IPC: B01J8/22
Filed: 1991-04-23
Abstract: ABSTRACT OF THE DISCLOSURE    A resid refining reactor has an ebullated catalyst bed. Hydrogen gas is released into the catalyst bed at a point which is far enough above a distributor plate at the bottom of the catalyst bed to form a gas updraft in a committed zone through the bed. This committed updraft causes a reduction in gas holdup which increases the residence time of a liquid phase in the catalyst bed.

Title: Wet multiple disk clutch apparatus which is used in vehicles
Inventor: ENOMOTO HIROKAZU
IPC: F16D13/68
Filed: 1991-04-25
Abstract: A plurality of facing plates provided for a hub fixed to an output shaft are alternately arranged for a plurality of steel plates provided on the clutch drum side fixed to an input shaft.  Projections are formed on an outer periphery of the steel plate.  Leaf springs are interposed between the projections of the adjacent steel plates by supporting by guide pins.  When the clutch is turned off, in a state in which a piston has backwardly been moved, a plurality of steel plates are widened by leaf springs so as to make the gaps among the plurality of steel plates uniform, thereby completely cutting off the frictional contact between the steel plates and the facing plates.

Title: Technique for laser cavity pumping
Inventor: RUMBOLDT CLAUDIO
IPC: H01S3/093
Filed: 1992-05-08
Abstract: IMPROVED TECHNIQUE FOR LASER CAVITY PUMPING                 ABSTRACT OF THE DISCLOSURE The invention concerns a tightly coupled diffusion pumping cavity in DaSO4 for a Laser or operating at low repetition on frequency, without a cooling  device, where the Laser (Figure 1) consists of an active material rod (1) set between two lamps (2), of a metal casing (5) which is in direct contact with the diffusing e-lement (4), where the casing may also act as a sup-port of such diffusing element, while this may be set in any preferred position.          Cooling is achieved by exploiting the radiation ex-change between the active material rod and the cavity itself.          The invention is best applied to those Lasers which require a compact design due to space constraints, as in the case of avionic and space-borne applications.
Patent CA-2069605-A1 (CA)
Inventor: CHASE NOEL E
IPC: B63H21/175
Filed: 1992-05-26
Abstract: Many human powered boats have been developed, including designs with rigid hulls and paddle wheels or screw pro-pellers, bicycle-type frames on rigid and inflatable pontoons, and flotation wheels on a bicycle frame. Ultimately, a reclining bicycle frame mounted on hydrofoils, supplemented with pontoons and using an air screw propeller is the design that currently holds the human-powered speed record on water.      This invention addresses the failings of a type of human powered boat which allows a conventional bicycle to be supported on and used to drive a collapsible boat. The entire boat can be stowed on the rack above the rear wheel.      It has two inflatable pontoons and a light, collapsible frame. The rear wheel rides on a split roller which, through a series of miter gears, drives a screw propeller. The front wheel is connected to a hinging swivel which in turn is connected to the forward rudder and/or propeller housing.    This invention allows the user to bicycle to a lake, inflate and assemble the boat, boat across the lake, disassemble and stow the boat and continue bicycling again.      Additional features, such as a reverse drive, combined forward and rear steering, and hinging couplings on the forward rudder and rear drive assemblies to minimize damage from submerged logs are included in this invention. Finally, a series of performance boats with rigid hulls and with the same forward rudder and/or rear drive assemblies are shown.      While this application is primarily about human powered boats, the configuration of a motorcycle is essentially the same as a bicycle. Many of the features disclosed could apply to a motorcycle boat, albeit necessarily stronger to support the additional weight of the motorcycle.

Title: Calibration method for automated assay instrument
Inventor: LONG ERNEST W
IPC: G01N35/10
Filed: 1992-02-03
Abstract: ABSTRACT OF THE DISCLOSURE             A method of calibrating pipette position in an automated assay instrument employing a conveyor for holding assay cartridges and a transport for transporting a pipette between various locations is accomplished by alignment of a pipette stem with targets located at various locations within the system. Two targets are located on a tray having a plurality of reservoirs for holding liquid, and one target is located on a dummy cartridge carried by the conveyor. An indicator having a spring-loaded tab is used in conjunction with a pipette stem modified by inclusion of a circumferential slot for receiving the spring loaded tab. The stem is inserted into the indicator and locked therein, with limited sliding being provided by movement of the tab within confines of the slot. Alignment marks are provided on both the stem and the indicator to permit visual alignment of the stem relative to a target upon abutment of the indicator with the target. The height of the indicator along with the displacement of the stem from a reference position is inserted into a microprocessor of the assay instrument.

Title: Linear inpact ripper apparatus
Inventor: JENSEN BRIAN D
IPC: E21B1/26
Filed: 1990-01-19
Abstract: Impact rippers are useful, for example, in fracturing rock and other hard material which is to be excavated. Known systems using structures which mount the impact hammer and the linear ram within a single housing transmit vibrations into the mounting frame and are difficult to service and expensive to maintain. The subject linear impact ripper apparatus (10) has an impact hammer (20) having one end (102) resiliently mounted to a mounting frame (14) and another end (104) slidably mounted on one of the linear ram (18) and the tool holder (16). Thus, the disclosed linear impact ripper apparatus (10) reduces vibrations transmitted to the mounting frame (14) and has separate elements for ease of service and reduced maintenance cost and maintains the alignment between the separate parts of the structure. The arrangement allows the connection between the impact hammer (20) and one of the linear ram (18) and the tool holder (16) to be sealed from atmosphere.
